Huh. My memory of TNG was that it was mostly variations of pasty off-white. The LCARS was colorful, but the uniforms were mostly primary colors and everything else was... well, pastel always seems watered-down and bland to me.
DS9 was all browns and blacks, though. It totally made sense, because of the station's history, but the colors were pretty monotone, like everything was dark sepia, right?
